Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hair member 11S, and more particularly to a joint part 2 attached to one end of a hose, and particularly to a one-piece member that can be attached to a hydraulic hose.

1lIl! The E-hose is connected by a coupling member to one end of a fluid source or other hose for moving the Tomiguchi book. This coupling member may be threaded or provided with other means for connection to other coupling members.

Even in cases where a hose is used to transport high-pressure fluid, the joint member must be securely attached to one end of the hose so that it does not slip away from the hose. Usually, a small fitting attached to one end of the hose has a nipple that fits into the hole in the hose or a shell that is wound around the stem in a substantially concentric circle around the outer bag of the hose. I've been away for a month.

After loosely fixing the heel member to one end of the hose, put it into a swage processing device and reduce the diameter of the joint.
Tighten the hose wall between the nipple and the shell.

However, such a conventionally used 4-man hose handles high-pressure fluid.
As for what should be added, it has been previously proposed that a fitting part be installed between the shell and the hose and the fitting should be tightened more firmly than the hose. For example, 1

No. 57.35'9 shows one piece that fits into the wall of the hose, and a flat piece with a sharp claw on the top. Also, US Pat. No. 2,314,000 discloses a segment insert having a protrusion between the nipple and the shell. The oil filler 81j has one end facing the nipple lane, and protrusions are arranged on the outer surface of the hose to sink into the hose wall. A hose with a similar insert under the nonyl of the two-wire hand member or 1923 9

Disclosed in the issue. Additionally, other types of inserts have been proposed that have protrusions that can be inserted between the outer surface of the hose and the girder, all of which require additional parts to manufacture and assemble the fitting. In addition, in order to fix the joint so that it does not come off the end of the hose that handles high-pressure fluid, the shell has to be
There is a problem that there is a gap around the smooth r-side surface of the human member.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide an improved coupling member for securing to one end of a hydraulic hose. Another object of the present invention is to provide an improved four-hand member that will not separate from the hose even under high ICE'F conditions. Still another object of the present invention is to provide a main hand member having a shell having fixing means for fixing it to one end of a hydraulic hose used under high pressure.

Other purposes will be apparent from the following description and accompanying drawings.

Generally, the present invention has a sharp tip and is inserted into the exterior of a hydraulic hose to provide reinforcement (tightly inter-strand reinforcement) around the core tube circumference 114 of the hose. A joint with a nipple or a stem part, which has a shell with i = number of protrusions with sufficient length for insertion, with l"sl i'R'+ openings around the inner wall. In the present invention, in order to avoid the bulge of the hose, the hose is press-fitted near the opening of the shell]1
Provide means for removing loaded acids. The If,i@ cargo removal means preferably includes one or more annular iA provided in the inner shell wall spaced longitudinally from the shell opening in the coupling member body. Included.

Further, the present invention provides a plurality of protrusions or rings in one or more rows provided at intervals around the inner wall of the shell, which fit into the exterior of the hydraulic hose, and are provided around the core tube 121j of the hose. This also includes the hydraulic hose with the new 4-hand part installed between the reinforcing strands.

One method of manufacturing the joint shell includes, for example:
One method is to extrude and raise an aluminum or aluminum metal tube having a plurality of longitudinally extending ribs having a triangular cross section at intervals around the inner wall. This extruded tube is cut to a length that matches the desired shell, fixed with a chuck, a forming tool is inserted into the tube, and the ribs are cut to form pyramid-shaped protrusions on the inner wall of the tube.

This method is disclosed in US Patent Application No. 753.897, filed Dec. 23, 1976.

Alternatively, it is possible to use a tube with a ring-shaped protrusion of triangular cross-section on the inner wall, insert a broaching tool into the tube, and pull it in the direction of the tube to form a protrusion from this ring. In addition, the shell (how about nylon?
It can also be obtained by forming protrusions on the inner layer of metal by casting metal such as steel.

Describe the cape and its attachment to one end of the hose. An extruded aluminum tube 10 having a plurality of ribs 11 spaced around the inner wall and extending in the longitudinal direction is shown in the hanging 11. The ribs 11 form a 11117-sided triangle as shown in FIG.

A forming tool is filled with oil in the tube 10, and the tube is rotated to form a hard pyramid-shaped protrusion 12 integral with the circle/protrusion 13 of the tube 10 and fλ. e)
The tool shown in Figure 3; in this example, the protrusions 12 are provided in two rows around the inner wall 13 with a space between them. In this figure, there are eight protrusions 12 in each row. The number of protrusions may be increased or decreased depending on the size of the hose and the pressure to which the hose to which the coupling member is attached is exposed, or one or more rows of protrusions may be provided.

As shown in Figure 5, one end of the tube 10: and, as shown in Figure 4.
A pair of numbers 14 and 15 are carved at intervals in the vertical direction on the inner wall between the parts having the pyramid-shaped protrusions 12 shown in the horizontal view of the housing 1.

shows. Loosely insert the nipple (stem) 24 of the coupling member into the hole of the core tube 26 at one end of the hose 21. Insert the hose with this 4-handed BIS side inserted into the swage and shorten the 1 line to the shell 10,
The protrusion 12 is attached to the exterior 27 of the hose 21, and the pointed end is llI Infiltrate the extortion layer 2S.

When the nonyl IOA is compressed 1-IE onto the piece of hose 21, the sheath 27 is forced into the groove 14.15 and into the removal site 29. The synthetic resin sheath will produce a cold flow when the hose end is compressed, and the space provided by 14, 15 and the removal site 29 will be sufficiently adjusted to avoid the balloon of the sheath on the outside of the nonyl IOA end.

As mentioned above, the shell IOA is preferably manufactured from an extruded aluminum tube, an aluminum alloy,
It may be made of steel, brass or any other suitable metal.

As mentioned above, it is preferable to form the internal protrusions by cutting the internal ribs, but other methods described above may also be used. For example, a suitable metal layer or synthetic polymer may be extruded to form a tube with a smooth inner wall surface. Next, after carving an N-shaped groove in the inner surface of the tube to form two screens of the protrusion, a broaching tool is inserted into the tube and pulled to cut the groove in the shrinking direction to create the other i+i of the protrusion. +
It is possible to form a surface. Although the protrusions can be formed by punching holes in the shell, this is not preferred because of the appearance of the punched shell. The shell can also be cast with the desired arrangement of projections or, more preferably, the projections may be formed by extrusion and machining.

In particular, in the case of a 1-piece hose, the shape of a circle 41r or the shape of a 1:It; rλ hard, three-dimensional protrusion, j
Good results can also be obtained with 4Q combination. Preferably, the protrusion has a sharp tip so that it can easily penetrate the fiber layer when cut in a straight line. Triangular protrusions can be used for some types of hoses, but a three-dimensional protrusion such as a circle d'< (or a pyramid-shaped protrusion) is stronger and preferable. The term "-koni-dimensional protrusion" means a protrusion with a base having a protrusion having W physical dimensions in both the horizontal and horizontal directions, and the minimum ζ' method (shadow, This protrusion (length) is larger than the thickness of the provided shell, and is therefore different from the triangular protrusion that is made to protrude by cutting out the shell and having a thickness equal to the thickness of the shell. Preferably, the three-dimensional protrusion (having a square or circular base and tapering downwardly toward the combed tip. The base of the protrusion does not need to be symmetrical, but has a substantially It is preferable that it be symmetrical.

Good results with joints made of aluminum, nylon, polyethylene, polyurethane
It may also be a synthetic polymer two-handed member.

Particularly advantageous are hoses with a synthetic polymer core, such as the hose described in No. 05.398. As described in these patents, the core tube may be extruded from nylon, polyurethane or other synthetic polymers. The core tube stiffener layer may be a fibrous material such as braided, spiral wrapped, or braided fibers such as nylon, polyethylene terephthalate ester, aromatic polymer, or the like. The exterior is made of nylon, polyethylene, or polyurethane.
